NHTSA Complaint #11674119 — 2019 RAM 1500

The dangerous behavior occurs only when the truck is in four-wheel-drive. Two behaviors: One:Low range. Ascending up a steep dirt road without warning truck shifted into neutral and got stuck there. Shifting into reverse drive or park did not take it out of neutral. The steering and brakes worked. The four-wheel-drive, low and four-wheel-drive high indicatorlights were blinking simultaneously. This behavior persisted after turning the truck off and on again. I had to back down a switchback dirt road. Eventually, I thought to disconnect the battery and reconnect it which corrected the behavior and put the truck back to normal. I no longer use this truck in four-wheel-drive low. I am having the truck looked at by a second dealer service department to try to diagnose this problem. 2: the second abnormal, behavior occurs in four-wheel-drive low, first gear heading downhill using the engine compression for braking. The truck will without warning shift into 2 Wheel Dr. high range, and the four-wheel-drive, low and four-wheel-drive high indicator lights blink simultaneously. This behavior is corrected by turning the engine off and then on again.
